In social insects, as queen number increases, individual oviposition rate may decrease because of direct and indirect behavioural and/or chemical interactions. Understanding the factors that mediate differences in queen fecundity should provide insight into the regulation and maintenance of highly polygynous insect societies, such as those of the invasive Argentine ant (Linepithema humile). In this study, we investigated (1) whether differences in the oviposition rates of Argentine ant queens exposed to polygynous conditions could result from interactions among them; (2) whether such differences in fecundity stemmed from differences in worker attention; and (3) whether polygynous conditions affected the cuticular hydrocarbon profiles of queens (CHCs). We found that differences in queen fecundity and CHC profiles observed under polygynous conditions disappeared when queens were exposed to monogynous conditions, suggesting some form of reproductive inhibition may exist when queens cohabit. These differences did not seem to arise from variation in worker attention because more fecund queens were not more attractive to workers. Levels of some CHCs were higher in more fecund queens. These CHCs are associated with greater queen productivity and survival. Our findings indicate that such compounds could be multifunctional queen pheromones" , "dc.description.sponsorship": "This work was financially supported by the Spanish Ministry of Science and Innovation and the European Regional Development Fund (CGL2010-16451)" , "dc.format.mimetype": "application/pdf" , "dc.language.iso": "eng" , "dc.publisher": "Nature Research" , "dc.relation": "CGL2010-16451" , "dc.relation.isformatof": "Reproducció digital del document publicat a: https://doi.org/10.1038/s41598-020-77574-1" , "dc.relation.ispartof": "Scientific Reports, 2020, vol. 10, art, núm. 20484" , "dc.relation.ispartofseries": "Articles publicats (D-CCAA)" , "dc.rights": "Attribution 4.0 International" , "dc.rights.uri": "http://creativecommons.org/licenses/by/4.0/" , "dc.subject": "Formiga argentina" , "dc.subject": "Argentine ant" , "dc.subject": "Animals invasors" , "dc.subject": "Introduced organisms" , "dc.subject": "Invasions biològiques" , "dc.subject": "Biological invasions" , "dc.subject": "Formiga argentina -- Fecunditat" , "dc.title": "Reproductive inhibition among nestmate queens in the invasive Argentine ant" , "dc.type": "info:eu-repo/semantics/article" , "dc.rights.accessRights": "info:eu-repo/semantics/openAccess" , "dc.relation.projectID": "info:eu-repo/grantAgreement/MICINN//CGL2010-16451/ES/LOS FORMICIDOS COMO INDICADORES DEL IMPACTO DE LA FRAGMENTACION, EXPLOTACION E INVASION DE LA HORMIGA ARGENTINA EN BOSQUES DE PINUS PINEA PINUS PINASTER/" , "dc.type.version": "info:eu-repo/semantics/publishedVersion" , "dc.identifier.doi": "https://doi.org/10.1038/s41598-020-77574-1" , "dc.identifier.idgrec": "032279" , "dc.contributor.funder": "Ministerio de Ciencia e Innovación (Espanya)" , "dc.type.peerreviewed": "peer-reviewed" , "dc.relation.FundingProgramme": "Subdirección General de Proyectos de Investigación" , "dc.relation.ProjectAcronym": "LOS FORMICIDOS COMO INDICADORES DEL IMPACTO DE LA FRAGMENTACION, EXPLOTACION E INVASION DE LA HORMIGA ARGENTINA EN BOSQUES DE PINUS PINEA PINUS PINASTER" , "dc.identifier.eissn": "2045-2322" , "dc.identifier.PMID": "33235272" , "dc.identifier.PMCID": "PMC7687882" }
